LMV7275IDCKRQ1 from Texas Instruments, in a SC-70-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN+ | input | Non-inverting comparator input. |
| 2 | V- | power_in | Negative supply voltage; the datasheet specifies single-supply operation at V- = 0 V with V+ from 1.8 V to 5.5 V. |
| 3 | IN- | input | Inverting comparator input. |
| 4 | OUT | output | Comparator output, an open-drain stage that allows wired-OR configurations and can be pulled up to any voltage up to 5.5 V regardless of the supply voltage. |
| 5 | V+ | power_in | Positive supply voltage, specified from 1.8 V to 5.5 V. |
